Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed November 8,1905. Serial No. 286,411.

To all whom it may concern.'

Be it known that I, :THOMAS BABBITT, a

.citizen of the United States, residing at Malad, in the county of Oneida, State of Idaho, have invented certain new and useful Improvements in Spindles and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to vehicle-axles.

One object is to provide an axle embodying such characteristics that in the event of wear or breakage of its spindle it will not be necessary to weld or otherwise secure a new spindle to the axle.

Another object resides in the provision of a sleeve adapted to fit over worn or broken spindles of axles in the event of wearing away or breaking of the spindle in combination with means associated with the axle and the sleeve to obviate the rattlingnoise occasioned by the wheel in its coperation with the spindle.

With these and other objects in view the present invention consists in the Combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a side elevation of a worn axle,illustrating the application of my invention thereto, parts being shown in section. Fig. 2 is an enlarged detail perspective view of one metallic and one yieldable washer, showing the legs of the former passing through the latter.

Referring now more particularly to the accompanying drawings, the reference character 1 indicates an axle provided with a spindle 2, there being an annular shoulder 3 at the base of the spindle. These elements are old and common in the art. As the" result of continual revolution of ,the wheel (not shown) upon the spindle 2 the latter becomes worn, resulting in wabbling of the wheel. There are other times when the spindle becomes accidentally broken. Heretofore when the spindle has become worn or broken it has been customary to weld or otherwise form a new spindle upon the corresponding end of the axle. I overcome this securing of a new spindle to the axle through the instrumentality of a sleeve 4. Before the sleeve 4 is placed upon the spindle 2 I screw-thread the inner end of the spindle, as at 5, and also screwthread the outer end of the spindle, as at 6, the extremity of the outer end of the spindle being reduced in cross-section and screwthreaded, as indicated by the reference character 7. Either before or after forming these screw-threads of the spindle I form upper and lower perforations S in the aforesaid shoulder 3 for a purpose presently explained. The inner end of the sleeve 4 is enlarged in cross-section, as indicated by the reference character 9, resulting in the formation of a shoulder 10, adapted to bear against the inner end of the screw-threads 5 of the spindle. The interior of the enlarged portion 9 of thc sleeve 4 is screw-threaded for cooperation with the screw-threads 5 of the spindle, and it has its inner end provided with an annular flange 11. This annular flange does not contact with the corresponding face of the annular shoulder 3, but provides a space therebetween. This space is not left vacant, but is filled through the instrumentality of a rubber washer 12 and a metallic washer 13, the metallic washer 13 being provided with upper and lower legs 14, designed to pierce the r'ubber washer 1 2 and be passed through the aforesaid perforations S of the shoulder 3. These legs 14 of the metallic washer 13 lit loosely in the perforations 8, so that a free movement of the washer 13 may be had upon compression of the rubber washer 12. The extremities of the legs 14 may be upset as indicated by the reference character 15. It is obvious with the shoulder 3, sleeve 11, and the metallic washer 13, will prevent a rattling noise incident to well-known reasons.

The outer end of the sleeve 4 is interiorly screw-threaded for cooperation with the screw-threads 6 of the spindle 2, as shown. Ordinarily this screw-threaded engagement of the sleeve 4 with the spindle 2 will prevent displacement of the sleeve. However, I provide a nut 16 for engagement upon the reduced extremity '7 of the spindle 2, which is provided with an inner annular hub-retaining flange 17. This flange is provided with upper and lower perforations 18 and is normally spaced from the sleeve 4. This space is iilled that this rubber washer 12, in its cooperation 9 the adjacent rubber washer 19.

by a rubber washer 19 and a metallic washer 20, provided with upper and lower legs 21, designed to be passed through the corresponding upper and lower perforations 18 of the flange 17 of the nut 16 and also through This disposition of the two kinds of washers 18 and 19 at the outer end of the spindle prevents a rattling noise incident to well-known reasons7 and the association of the said washers and the nut 16 with the outer end of the spindle 2 prevents accidental displacement of the sleeve 4 with respect to the spindle. As a further means of preventing accidental displacement of the sleeve 4 from the spindle 2 I provide a key 22, designed to be passed through alining perforations of the sleeve 4 and spindle 2, as shown.

From the Jforegoing it will be appreciated that the sleeve 4 serves in the capacity of a skein, and in the claimsI I shall refer to the sleeves as a skein What is claimed is- 1. The combination with an axle provided with a spindle, the axle having a perforated shoulder at the inner end of the spindle, and the spindle having a reduced outer end; of a skein removably fitted upon the spindle, a pair of washers fitted between the inner end of the skein and said shoulder, one of the washers having legs piercing the other washer and passed through the perforations of the shoulder, and means fitted upon the reduced end of the spindle to prevent accidental displacement of the skein with respect to the spindle.

2. The combination with an axle provided with a spindle, the axle having a perforated shoulder at the base of the spindle, of a skein removably fitted upon the spindle, a yieldable washer, and a metallic washer fitted between the inner end of the skein and said shoulder, the metallic washer having legs passed through the yieldable washer and the perforations of the shoulder, and means engaged with the spindle and skein to prevent accident al displacement of the latter with respect to the former. 3. The combination with an axle provided with a spindle having a reduced outer end, the axle having a perforated shoulder at the base of the spindle, of a skein fitted upon the spindle, a yieldable and metallic washer fitted between the inner end of the skein and the shoulder, the metallic washer having legs passed through the yieldable washer and the perforations of said shoulder, a nut fitted upon the reduced outer end of the spindle, and a yieldable washer fitted between the nut and the outer end of the skein, the metallic washer having legs passed through its adjacent yieldable washer and the said nut. y

In testimony whereof I affix my signature in presence of two witnesses.
